Short-term toxicity tests are available for all three trophic levels (fish, invertebrates and algae).
A GLP-compliant OECD guideline 203 study is available for EEA-NH4 (Kurume Laboratory, 2006b). In this semi-static limit test with analytical monitoring a 96-h LC50 value of >100 mg/L (nominal concentration) was observed in medaka (Oryzias latipes).
A GLP-compliant OECD guideline 202 study is available for EEA-NH4 (Kurume Laboratory, 2006c). In this static limit test with analytical monitoring a 48-h EC50 value of >100 mg/L (nominal concentration) was observed inDaphnia magna.
A GLP-compliant OECD guideline 201 study is available for EEA-NH4 (Kurume Laboratory, 2006d). In a limit test with analytical monitoring a 72-h EC50 value of >100 mg/L and a 72-h NOErC of <100 mg/L (nominal concentrations) were observed inPseudokirchneriella subcapitata.
Furthermore, a GLP-compliant OECD guideline 209 study is available for EEA-NH4 (NOTOX, 2008). In this study with activated sludge from a municipal sewage treatment plant a 3-h EC50 value of >100 mg/L was determined.
The L(E)C50 values were >100 mg/L for the three trophic levels tested (fish, invertebrates and algae). Therefore the substance does not need to be classified according to Directive 67/548/EEC and EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008.
